Members of the band thanked their family, for putting up with all the years that the band toured and made no money and lived at home. A reminder that success takes time and is riddled with failures.
As the backgroud music began to play, and members of the band squeezed out their last thanks yous, they danced along to the music that is meant to irritate them into getting off the stage.
One of those "thanks yous" was to Jay-Z, who shouted back, "Your welcome," with a drink in hand. Is he drunk already?!
